Expressing the translocation domain of colicin A in the periplasm and challenging the cells with external colicins showed that the translocation of group A colicins is inhibited as it requires an interaction with the Tol system. Surprisingly, the TolA protein was found to play the major role during the translocation of both ColA and the endonuclease colicin E9 even though the latter colicin has no direct interaction with the TolA protein. This study also suggests that the interaction with TolB is important for both colicins A and E9.

In the case of WannaCry, a cyber security specialist noted that it was contacting a domain name before it infected each computer, and would not infect the computer if it hadn’t gotten a reply. The researcher registered the domain name to slow its spread, apparently with success. The infected computers can be controlled remotely, for instance to carry out attacks to overload websites..

Obesity campaigners cautioned the results should not be seen as a green light to “let yourself go” when reaching middle age but added there was evidence gaining weight can be useful in protecting against fatal diseases.

“The Marksman,” a Liam Neeson thriller from Open Road, held onto first place for the second weekend in a row, grossing just over $2 million. The film has grossed $61 million after 10 days of release.That performance allows the movie to retain its box office crown, but that kind of distinction isn’t worth what it was in pre pandemic times, particularly with movie theatres closed indefinitely in major markets like New York City and Los Angeles.Indeed, the exhibition landscape is a wasteland and with the vaccine rollout hampered by a lack of, you know, vaccines, help could be in short supply. There’s little that portends a rapid recovery for a sector of the economy that’s been decimated by the public health crisis.
